In case this function is called by another thread than the mainthread

we emit a signal which is connected through "BlockingQueue"-Connection Type.

This cause that the current thread is blocked and waiting for the result.

Of course, in case this gets called from the mainthread we must not emit the signal,

but call the slot directly.
